The International Forum on Translation Technology will be held on the theme of cooperative work between humans and the computer. As an example of the cooperative work, the present situation and prospects for the machine translation value-added network (MT-VAN) service will be described below. In the MT-VAN, users, the machine translation systems and the translators are satisfactory linked by th...

Businesses that rely on a value-added network to provide information processing and communications services are only as secure as the network itself. The customer should understand the types of processing and control services provided by such vendors, and the potential exposures that use of these networks can entail. This article describes the control issues that must be addressed, the controls...

0 1 5 Frequency [GHz] 6 2 3 4 Abstract The validity of lumped element microwave class-F amplifier circuit design has been demonstrated experimentally. By means of the proposed class-F amplifier design method, more than 4th-order higher harmonic frequencies can be taken into account in class-F microwave amplifier design using only lumped element components. In this approach, miniaturization of c...

The emerging service-dominant logic requires cooperation between several partners in a value-added network or value chain. Information asymmetry and information gaps may lead to uncovered and unused knowledge. This paper addresses how this problem can be solved by suggesting an approach based on contingency theory. The core idea consists of supporting and improving value-added partnerships by e...

Two simple class-F NVI1VIIC power amplifiers are described using 0.7tm field-plated GaN HEMT devices. One circuit was designed for operation at 2.0 GHz and achieved a power-added-efficiency of 50%, 38 dBm output power, and 6.2 W/mm power density. A second circuit was designed at 2.8 GHz and achieved a PAE of 46% with 37 dBm output power and 7.0 W/mm power density.

In this study, balanced and single ended class-E power amplifiers (PAs) were designed and realized for 3.5–3.8GHz band by using Gallium Nitride high electron mobility transistor (GaN HEMT). Realizations were made on low loss Rogers RT5880 dielectric material which has 0.254mm thickness and 2.2 dielectric constant. Proposed balanced class-E PA has approximately 20W (43 dBm) output power with 80%...

Raising domestic tax revenues is a priority for most sub-Saharan African countries. But the tax bases in most African countries are undermined by widespread tax avoidance and evasion. A new study from CMI supports the claim that improved knowledge about the tax system makes a difference in people’s willingness to pay tax. The study shows that exposure to Value-AddedTax (VAT) makes people take a...

The objective of this research was to design a 2.4 GHz class AB Power Amplifier (PA), with 0.18um Semiconductor Manufacturing International Corporation (SMIC) CMOS technology by using Cadence software, for health care applications. The ultimate goal for such application is to minimize the trade-offs between performance and cost, and between performance and low power consumption design. This pap...
